the skyscraper booms in other sunbelt cities, such as Los Angeles and Dallas. Houston had experienced another downtown construction spurt in the 1970s with the energy industry boom. The first major skyscraper to be constructed in Houston was the 50-floor, tall One Shell Plaza in 1971. A succession of skyscrapers were built throughout the 1970s, culminating with Houston's tallest, the 75-floor, tall JPMorgan Chase Tower (formerly the Texas Commerce Tower), designed by I. M. Pei and completed in 1982. As of 2010, it is the tallest man-made structure in Texas, the 12th-tallest building in the United States and the 48th-tallest skyscraper in the world. Pennzoil Place, designed by Philip Johnson and built in 1976, is Houston's most award-winning skyscraper and is known for its innovative design. The 46-story One Houston Center, which was built in 1978, is 207 m (678 ft) tall and was designed by S.I. Morris Associates, Caudill Rowlett Scott, and 3D/International. The Fulbright Tower, built in 1982 and designed by Caudill Rowlett & Scott Architects, is a 52-story tower constructed of steel with suspended concrete on metal deck floor slabs. The exterior wall consists of a ribbon window wall with granite spandrel panels and aluminum framed windows with insulated glazing. The spandrel panels are polished granite supported by a steel truss system. The interior wall surfaces are constructed of Italian flame cut Rosa Beta granite, quarried in Sardinia, mixed with Makore wood and stainless steel trim. In 1983, the Wells Fargo Bank Plaza was completed, which became the second-tallest building in Houston and in Texas, and the 11th-tallest in the country. It was designed by Skidmore, Owings & Merrill and Lloyd Jones Brewer and Associates and supposedly resembles an abstracted dollar sign in plan. From street level, the building is 71 stories tall, or 972 ft (296 m) tall. It also extends four more stories below street level. The Bank of America Center is one of the first significant examples of postmodern architecture built in downtown Houston. The building, completed in 1984 and designed by Philip Johnson and partner John Burgee, is reminiscent of the Dutch Gothic architecture of canal houses that were once common in The Netherlands. The first section is 21 stories tall, while the whole building reaches a height of 56 stories. Heritage Plaza is a 53-story, 232 m, tower in downtown. The building, designed by M. Nasar & Partners P.C., was completed in
